Since the outbreak of the Iran war in late February, Tehran has severely restricted traffic through the strategic waterway, insisting vessels use routes authorised by the Islamic republic.

The US has in response imposed a naval blockade on Iranian ports and helped tankers travel the strait, which normally carries about one-fifth of global oil consumption.
